Which format should I use?

In general you should use the voice-pack matching the most common codec used on your Asterisk system. If
your Asterisk system uses several codecs, you may want to use the native Asterisk format.

Asterisk Native (sln) - Highest quality
Sound files in the sln format are not compressed and have the highest dynamic range and quality. Asterisk
will compress these sound files on the fly with the appropriate codec for the particular channel. If your
Asterisk system uses different codecs for different interfaces/clients, this format will present the best
quality for each codec.

G.711 μ-law/a-law - Good quality (recommended)
G.711 μ-law is the ITU standard for the digital telephone network in North America and Japan, and a-law in
the rest of the world. If you are connecting to the telephone network through a T1 (μ-law) or E1 (a-law),
sound files in this format can be streamed directly to the digital interface without any overhead for
transcoding. In most Asterisk implementations that are based on interconnection to the public telephone
network, the G.711 voice-pack for your region is generally the best choice.

GSM - Moderate quality
GSM is a low-bandwidth compression standard used in cellular phone systems in many parts of the world, as
well as in many VoIP systems. Because the compression reduces the quality of the sound files, voice-packs
in this format are intended primarily for Asterisk systems which only use GSM. If any interfaces on
the Asterisk system use a higher quality codec, users will notice a distinct quality difference between
GSM-compressed sounds files and the higher-quality versions.

These voice-packs are designed to replace the default voice-pack that ships with the Asterisk software.
Once you have downloaded the desired voice-pack to your Asterisk server, installation is performed with
the following commands:

Where voicepack.tgz is the voice-pack file downloaded
from this page. If you are using a non-standard installation, change /var/lib/asterisk to the folder than contains the sounds
folder.

Once you have installed the free voice-pack, order recordings in the same voice to customize the voice-pack for
your organization. Create custom IVR's, hold messages, advertisements-on-hold, and internal feature prompts.
